Question

What is the length of MN¯¯¯¯¯¯¯ ?

Round to the nearest tenth of a unit.

Answer 1

Answer: ^^that person is correct the answer is 8.5 Units

Explanation:

Answer 2

Find out the length of MN .

To prove

Formula

`Distance\ formula = \sqrt{{(x_(2) - x_(1))^(2) +{(y_(2) - y_(1))^(2) }`

Two points be M (2, -2) and N(8,4) .

Put in the formula

`Distance\ formula = \sqrt{{(8 - 2)^(2) +{(4 - (-2))^(2) }`

Solving the above

`Distance\ formula = \sqrt{{6^(2) +{6^(2) }`

`Distance\ formula = √(36+36)`

`Distance\ formula = √(2*36)`

`Distance\ formula = √(72)`

Distance formula = 8.5 unit (approx)

Therefore the length of MN is 8.5 unit (approx) .
